The third answer is not one of Newton's laws.
The second statement is Newton's first law (the law of inertia).
The last statement is Newton's second law.
The first statement is Newton's third law.
The four principles of natural selection are variability among members of a species, heritability of the variable features, differences in population members' ability to reproduce and survival of the fittest in terms of variability, heritability and reproduction. Natural selection is one of evolution's four mechanisms.
Answer:
D Africa
Explanation:
African leaders have pledged to devote more resources to the development of science and technology, an area deemed vital for economic development, yet long neglected and poorly funded in many countries. At a January 2007 summit of the continent’s political body, the African Union, heads of state “strongly urged” all AU countries to allocate at least 1 per cent of their gross domestic product to research and development by 2020. They also pledged to revitalize African universities — many of which have declined due to dwindling support over the last few decades — and to promote the study of science and technology by young people.
The remaining ratio of alleles is about 3:1
<h3>What about alleles?</h3>
- The term "allele" is employed to refer to a gene's alternate form or variants.
- For each autosomal gene, one allele is inherited from each parent, and that we often group the alleles into groups.
- Usually, we ask them as normal, wild-type, aberrant, or mutant alleles.
- For instance, a dominant allele can overcome the characteristics of other recessive alleles;
- These features are what determine an individual's eye and hair color, for instance .
- In this instance, the dominant brown eye alleles outnumber the recessive blue eye alleles.
- Any of two or more genes that may alternately appear at a certain location (locus) on a chromosome is referred to as an allele, also referred to as an allelomorph.
- Alleles may exist in pairs or there could also be many alleles influencing how a certain trait is expressed (phenotype).
- Each gene during a human has two copies (or alleles), one from each parent.
- Alleles significantly contribute to the event of each person's unique traits.
- Alleles are variants of the identical gene with a minor difference in the DNA base sequence.
- An allele may be a gene's variable form.
- Some genes exist during a number of forms, all of which share the identical genetic locus on a chromosome.
- Because each genetic locus in humans has two alleles—one acquired from each parent—they are referred to as diploid creatures.
